Answer:

Geosphere and atmosphere.

Explanation:

Earth is a planet that has multiple systems, and even though all of them are unique with their own characteristics, they are all connected, influence each other, and depend on each other in many ways. Two of those systems or spheres are the geosphere and atmosphere, with the geosphere being represented by the crust, while the atmosphere is represented by the air above the surface of Earth.

In this case, we have desert winds blowing sands across the dunes. The desert winds, or any winds for that matter, are air masses, thus they belong to the atmosphere. The sands are sediments, thus they are formed from rocks that have broken apart, meaning that they belong to the geosphere. The conclusion is that the winds as being part of the atmosphere and sands being part of the geosphere create a situation where these two spheres interact with each other.

The great plains characteristics

Natasha_Volkova [10]

The Great Plains have a continental climate. Over much of their expanse, cold winters and warm summers prevail, with low precipitation and humidity, much wind, and sudden changes in temperature. The major source of moisture is the Gulf of Mexico, and the amount falls off both to the north and west.

Why do earth quakes often happen near volcanic regions

Kaylis [27]

Answer:

Most earthquakes directly beneath a volcano are caused by the movement of magma. The magma exerts pressure on the rocks until it cracks the rock. Then the magma squirts into the crack and starts building pressure again. Every time the rock cracks it makes a small earthquake.

ABCD, GB is parallel to AK, AC is congruent to DB, GB is perpendicular to BD, KC is perpendicular to AC

AleksandrR [38]

Answer:

The two column proof is given as follows;

Statement ${}$ Reason

1. $\overline {ABCD}$ , $\overline{GD}$ \\ $\overline {AK}$ , $\overline{AC}$ ≅ $\overline {DB}$ ${}$ Given

$\overline{GB}$ ⊥ $\overline {BD}$ , $\overline{KC}$ ⊥ $\overline {BD}$

2. ∠KCA = ∠GBD = 90° ${}$ Given

3. Therefore,

4. ∠KAB = ∠GDC ${}$ Alternate interior angles

5. ΔGBD ≅ ΔKCA ${}$ By ASA rule of congruency

6. $\overline{GB}$ ≅ $\overline {KC}$ ${}$ By CPCTC

Explanation:

Given that two angles and an included side of triangle ΔGBD are equal to the corresponding two angles and an included side of triangle ΔKCA, therefore, ΔGBD ≅ ΔKCA by the Ange-Side-Angle rule of congruency, therefore, we have;

Segment $\overline{GB}$ is congruent to segment $\overline {KC}$ by Congruent Parts of Congruent Triangles are Congruent, CPCTC.
